接手幾個基於 Grails 2.3.11 的老專案，用 SDKMan 很方便的安裝好 OpenJDK 8 與 Grails 開發環境後，開始一陣操弄

grails clean

先碰到 Resolve error obtaining dependencies 錯誤，因為 maven repositories 網址都改變了需要手動替換 mavenRepo 設定

grails compile

相依性處理到沒問題後

grails run-app

炸了，錯誤訊息節錄如下:

搜尋網路後發現最低從 1.8.0_40 版本開始碰到相同問題

只好到 Oracle Java archive 去下載舊版 JDK

https://www.oracle.com/java/technologies/javase/javase8-archive-downloads.html

下載使用 Java SE Development Kit 8u40 版本測試確實會碰到問題

接著使用 Java SE Development Kit 8u31 版本可以讓 grails run-app 正常啟動，不過這樣的選擇是否能穩定運作無法保證。有疑慮可考慮改用 JDK 7 的最終版本。

查看 System/Overview 頁面，在 Indexer failures 有大量的失敗訊息：

錯誤訊息重點如下：

{“type”:”cluster_block_exception”,”reason”:”blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];”}

這是 Elasticsearch 服務的問題

先檢查儲存空間是否太少，使用空間超過 95% 就會 read-only

df -h

不過我遇到的狀況是使用空間不到 50% 後來猜測但會不會是記憶體容量問題 (雖然日誌都沒相關資訊)，將原本總量 8G 使用量在 4G 上下，停機增加到 16G 重啟後問題就消失了。

這是因為在 configuration.yaml 設定檔中有做 homeassistant 的設定，所以 Web UI 的編輯功能就鎖起來了。

可以參考官方說明來修改所需的屬性設定或是將設定檔內 homeassistant 的設定清除，然後重啟 Home Assistant 就可以在 Web UI 上直接編輯。

安裝 KB3138612：x64 系統的 Windows 7 更新 或 KB3138612：Windows 7 更新 就可以修復
